Does anyone have the matrix MPS 3005 power supply. I recently bought one from Amazon and it makes a weird series of clicks when I turn the output on or off. Not sure if this is normal or if I should return it. Here's a video of it: https://imgur.com/a/yL4NqSF |

Yes I have the 3605 and it does click when changing the voltage. It's a linear power supply and needs to switch transformer tap for the voltage ranges to prevent too much heat dissipation. |
